Page 4 WS1CI & WS1.25CI Manual Introduction This manual is about a control valve to be used on water softeners or water filters. The manual is designed to aid water treatment equipment manufacturers in the selection of the various control valve options. Information in this manual is different than what is needed for installation and servicing of a particular water treatment system. This manual is not intended to be used as a manual for a complete water softener or filter. Certain parts of the manual will serve as aids to manufacturers in the writing and layout of the manuals for installers and service personnel. General Warnings (Must appear in OEM s manual) The following general warnings and the specifications in Table 1 must appear in the OEM s System Manual. The control valve, fittings and/or bypass are designed to accommodate minor plumbing misalignments but are not designed to support the weight of a system or the plumbing. Do not use Vaseline, oils, other hydrocarbon lubricants or spray silicone anywhere. A silicone lubricant may be used on black o-rings but is not necessary. Avoid any type of lubricants, including silicone, on the clear lip seals. The nuts and caps are designed to be unscrewed or tightened by hand or with the special plastic wrench. If necessary a pliers can be used to unscrew the nut or cap. Do not use a pipe wrench to tighten or loosen nuts or caps. Do not place a screwdriver in the slots on caps and/or tap with a hammer. Do not use pipe dope or other sealants on threads. Use Teflon tape on threaded inlet, outlet and drain fittings. Teflon tape is not necessary on the nut connection or caps because of o-ring seals. After completing any valve maintenance involving the drive assembly or the drive cap assembly and pistons, press and hold NEXT and REGEN buttons for 3 seconds or unplug power source jack from the printed circuit board (black wire) and plug back in. This resets the electronics and establishes the service piston position. The display should flash all wording, then flash the software version (e.g. 316) and then reset the valve to the service position. All plumbing should be done in accordance with local plumbing codes. The pipe size for the drain line should be a minimum of ½. Backwash flow rates in excess of 26.5 lpm (7 gpm) or length in excess of 6.1 m (20 ) require ¾ drain line. Solder joints near the drain must be done prior to connecting the drain line flow control fitting. Leave at least 152.4 mm (6 ) between the drain line control fitting and solder joints when soldering pipes that are connected on the drain line control fitting. Failure to do this could cause interior damage to the drain line flow control fitting. When assembling the installation fitting package (inlet and outlet), connect the fitting to the plumbing system first and then attach the nut, split ring and o-ring. Heat from soldering or solvent cements may damage the nut, split ring or o-ring. Solder joints should be cool and solvent cements should be set before installing the nut, split ring and o-ring. Avoid getting primer and solvent cement on any part of the o-rings, split rings, bypass valve or control valve. Plug into an electrical outlet. Note: All electrical connections must be connected according to local codes. (Be certain the outlet is uninterrupted.) Install grounding strap on metal pipes.

Page 6 WS1CI & WS1.25CI Manual Control Valve Function and Cycles of Operation This glass filled Noryl 1 (or equivalent) fully automatic control valve is designed as the primary control center to direct and regulate all cycles of a water softener or filter. When the WS1CI control valve is manufactured as a softener, the control valve can be ordered to perform downflow or upflow regeneration. The WS1.25CI control valve is only available in downflow regeneration. When the WS1CI or WS1.25CI control valve is set up as a filter, the control valve can be set to perform downflow regeneration or simply backwash. The control valve can be set to regenerate on demand (consumption of a predetermined amount of water) and/or as a time clock (passage of a particular number of days). The control valve can be set so that a softener can meet the Water Quality As so ci a tion (WQA) Standard S100 or NSF/ANSI Standard 44 efficiency rating. It is not recommended to change control valves from downflow to upflow brining or vice versa in the field. The valve bodies for downflow and upflow are unique to the regeneration type and and should not be interchanged. A mismatch of valve body and regeneration piston will result in hard water bypass during service. The control valve is compatible with a variety of regenerants and resin cleaners. The control valve is capable of routing the flow of water in the necessary paths to regenerate or backwash water treatment systems. The injector regulates the flow of brine or other regenerants. The control valve regulates the flow rates for backwashing, rinsing, and the replenishing of treated water into a regenerant tank, when applicable. The control valve uses no traditional fasteners (e.g. screws); instead clips, threaded caps and nuts and snap type latches are used. Caps and nuts only need to be firmly hand tightened because radial seals are used. Tools required to service the valve include one small blade screw driver, one large blade screw driver, pliers and a pair of hands. A plastic wrench is available which eliminates the need for screwdrivers and pliers. Disassembly for servicing takes much less time than com pa ra ble products currently on the market. Control valve in stal la tion is made easy because the distributor tube can be cut 12.7 mm (½ ) above to 12.7 mm (½ ) below the top of tank thread. The distributor tube is held in place by an o-ring seal and the control valve also has a bayonet lock feature for upper distributor baskets The AC adapter power pack comes with a 4.6-meter (15-foot) power cord and is designed for use with the control valve. The AC adapter power pack is for dry location use only. The control valve remembers all settings for two hours if the power goes out. After two hours, the only item that needs to be reset is the time of day; all other values are permanently stored in the nonvolatile memory. The control valve does not need batteries. The control valve s unique design and electronics allow the OEM to select the regeneration cycle sequence, as well as the cycle times. The regeneration cycles available are: Backwash Rinse Downflow Brine Upflow Brine (WS1CI only) Fill/Regenerant Refill (this cycle can be set for either pre- or post-regeneration) Softening/Filtering (cycle used when regenerant is added just prior to the control valves scheduled regeneration). The cycle time entered should be long enough to dissolve the regenerant being used. Note: The control valve is in service during this cycle. End (will complete regeneration process and return control valve to service position) Tables 3 and 4 show examples when the valve is set up as a softener or filter.

If a control valve does not contain a meter, the valve can only act as a time clock, and day override should be set to any number and volume capacity should be set to off. Table 5 DIR Time Clock Reserve Capacity Softener Regenerant Filter Settings 3 Backwash Only Day Override Volume Capacity Yes Automatically calculated Yes Off Auto If desired enter a value less Any Yes Yes Yes Yes Off than estimated capacity Number Any Yes Yes Automatically calculated Yes Auto Yes Yes If desired enter a value less than estimated capacity Yes Yes Yes Yes None Yes Yes Yes Number Any Number Any Number Any Number Off For DIR Softeners, there are two options for setting the Volume Capacity. The Volume Capacity is automatically calculated if set to AUTO. Reserve Capacity is automatically estimated based on water usage if AUTO is used. The other option is to set the Volume Capacity to a specific number. If a specific number is set, reserve capacity is zero, unless the value is manually set (i.e. the manufacturer intentionally sets the volume capacity number below the calculated capacity of the system). The control valve can also be set to regenerate immediately or at the next regeneration time by changing the Regeneration Time Option. There are three choices for settings: 1. NORMAL means regeneration will occur at the preset regeneration time. 2. on 0 means regeneration will occur when the volume capacity reaches zero. 3. NORMAL and on 0 means the regeneration will occur at the preset regeneration time unless the volume capacity reaches zero. If the volume capacity reaches zero the regeneration will begin 10 minutes after no water usage. The user can initiate manual regeneration. The user has the option to request the manual regeneration at the delayed regeneration time or to have the regeneration occur immediately: 1. Pressing and releasing the REGEN button. Regen Today will flash on the display and the regeneration will occur at the delayed regeneration time. The user can cancel the request by pressing and releasing the REGEN button. This method of manually initiating regeneration is not allowed when the system is set to on 0, i.e. to immediately regenerate when the volume capacity reaches zero. 2. Pressing and holding the REGEN button for approximately 3 seconds will immediately start the regeneration. The user cannot cancel this request, except by resetting the control by pressing NEXT and REGEN buttons simultaneously for 3 seconds. The WS1CI & WS1.25CI control valves consist of the following components: 1. Drive Assembly 6. Drain Line Flow Control and Fitting Assembly 2. Drive Cap Assembly, Main Piston and Regenerant Piston 7. Water Meter or Meter Plug 3. Spacer Stack Assembly 8. Mixing Valve (optional) 4. Injector Cap, Screen, Injector Plug and Injector 9. Installation Fitting Assemblies 5. Refill Flow Control Assembly or Refill Port Plug 10. Bypass Valve (optional) Note: The WS1CI & WS1.25CI share many of the same components. Refer to Figure 6 for control valve identification. 2 See Installer Display Settings, OEM Softener System Setup and OEM Filter System Setup for explanations of Day Override and Volume Capacity. 3 Day Override and Volume Capacity can not both be set to off at the same time.
Page 8 WS1CI & WS1.25CI Manual Drive Assembly The drive assembly consists of the following parts: Drive Bracket Printed Circuit (PC) Board Motor Drive Gears Drive Gear Cover The drive bracket holds the PC board, the motor, the drive gears and the drive gear cover in place. The PC board receives and retains information, displays the information, determines when to regenerate and initiates regeneration. The display shows different types of information in the initial system set up (for softeners or filters), installer display settings, diagnostics, valve history or user display settings. The PC board powers the motor. The PC board s two-prong jack connects wires to the direct current (DC) motor. The motor is held in place on the drive bracket by a spring-loaded clip and a small bulge in the plastic, which fits in one of the slots on the motor housing. The motor turns drive gears that drive the piston to cycle positions for backwashing, regeneration, rinsing, refill or service. The motor is fully reversible (turns both ways) and changes direction of rotation to change the direction of piston motion. The motor is easily replaced if necessary. There are three drive gears held in place by the drive gear cover. All three drive gears are the same size. A reflective coating is applied to the gears. As the center drive gear turns a light shines on the coating and a light sensing diode determines if a light pulse was returned. The PC board counts the pulses and determines when to stop driving the motor. Drive Cap Assembly, Main Piston and Regenerant Piston The drive gears turn the main gear of the drive cap assembly, which moves the piston. The screw-driven, horizontally moving piston stops at specific positions to direct the flow of water to backwash, regenerate, rinse or refill. The PC board determines the position of the piston by counting pulses produced when the piston is moved. An optical sensor looking at one of the reduction drive gears generates these pulses. Each cycle position is defined by a number of pulses. The counter is zeroed each time the valve goes to the service position. The PC board finds the service position by noting the increase in current delivered to the motor when the mechanical stop at the service position is reached. This method of controlling piston position allows for greater flexibility and requires no switches or cams (U.S. Patent 6444127). One of three main pistons is always used: 1. 1.25" diameter downflow piston is used when the WS1CI control valve is used as a downflow softener, regenerating filter or non-regenerating filter. 2. 1.25" diameter upflow piston is used when the WS1CI control valve is used as an upflow softener. 3. 1.5" diameter downflow piston is used when the WS1.25CI control valve is used as a downflow softener, regenerating filter or non-regenerating filter. An upflow piston is not available for the WS1.25CI control valve. If the control valve is used as a softener or a regenerating filter, a regenerant piston must be attached to the main piston. If the control valve is to be used on a system that does not require a regenerant to be added, the regenerant piston must be removed. Spacer Stack Assembly The spacer stack assembly provides the necessary flow passage for water during the different cycles. The all-plastic spacer stack assembly (U.S. Patent 6402944) is a one-piece design which allows the stack to be removed using your fingers. The exterior of the stack is sealed against the body bore with self lubricating EPDM o-rings, while the interior surface is sealed against the piston using slippery self cleaning directional (one-way) silicone lip seals. The lip seals are clear in color and have a special slippery coating so that the piston does not need to be lubricated.
WS1CI & WS1.25CI Manual Page 9 Injector Cap, Screen, Injector Plug and Injector The screen, injector and/or injector plug(s) are installed under the injector cap in an easy to access location on top of the valve. The injector cap contains four slots so no water accumulates in the cap. The injector cap is designed to be hand tightened. Under the injector cap there is an easy to clean removable screen to prevent fouling of the injector. There are two holes under the injector cap labeled DN and UP. The holes will be filled with a plug or an injector. The plug (Order # V3010-1Z) prevents water from traveling a certain pathway. The injector lets water pass through the pathway. The self-priming injector increases the velocity of the water, creating a zone of negative pressure that draws in the concentrated liquid regenerant, such as sodium chloride (brine), potassium permanganate, etc. The regenerant blends with the stream of water, which passes through the media to regenerate the bed. The injector provides a consistent regenerant/water mixture ratio over the entire operating pressure range of the control valve. The injector provides good performance in a variety of applications, which may involve elevated drain lines and long regenerant draw lengths. Injectors are chosen by knowing the type, amount, and regenerant flow rate for a particular type of media. Guidelines can be found in the media manufacturer s literature. The color coded injectors give different regenerant draw, slow rinse and total flow rates over the pressure range. See Table 6 for color codings, and injector graphs for total, slow rinse and draw flow rates.

Separate areas in the valve supply water to the injector for upflow and downflow valves. Refill Flow Control Assembly or Refill Port Plug The refill flow control assembly consists of a refill flow elbow, refill flow control retainer assembly, refill flow control, polytube insert and nut assembly. The refill flow control retainer fits in the refill elbow. The refill flow control retainer houses the refill flow control which controls the flow rate when the regenerant tank is being refilled. The refill flow control is a flexible washer-like part with a small orifice and a precision molded contour that delivers a steady 1.9 lpm (0.5 gpm) regenerant tank refill rate at varying inlet pressures. Refill is accomplished with treated water. 4 Actual tank size used may vary depending on the design and application of the system. Tank diameter is an approximation for the following: 1. downflow softener using standard mesh synthetic cation exchange media regenerating with sodium chloride. 2. upflow softener using standard mesh synthetic cation exchange media regenerating with sodium chloride, an inlet water pressure of 2.1 to 3.4 bar (30 to 50 psi) and water temperature of 15.6 C (60 F) water or warmer. Higher pressures or lower temperatures would need smaller injectors to avoid lifting the bed.
Page 10 WS1CI & WS1.25CI Manual The refill flow control assembly is installed in an easy to access refill elbow located on top of the control valve. The refill flow control assembly is attached to the control valve with a locking clip. The locking clip allows the elbow to rotate 270 degrees so the outlet can be orientated toward the regenerant tank. The control valve has a standard refill elbow to which a 3/8 flexible tube can be connected. An optional elbow can be ordered which accommodates a ½ flexible tube for a high regenerant draw rate situation (G injectors and larger). Both elbows use the same refill flow control and retainer. If the control valve is to be used as a non-regenerant filter control valve, the refill elbow is removed and replaced with a refill port plug P/N V3195-01. Drain Line Flow Control and Fitting Assembly The drain line flow control assembly includes a drain line flow control and a fitting. The drain line flow control allows proper media bed expansion by regulating the flow rate to the drain. The drain line flow control is a flexible washer-like part with an orifice and a precision molded contour. The flow rates are within ± 10% over the pressure range of 1.4 bar (20 psi) to 8.6 bar (125 psi). See Table 7 for flow rate information.

The drain line flow control can be installed in the standard ¾ drain line elbow, which accommodates 5/8 polytube or ¾ NPT drain line connections. The optional nut and polytube insert for the ¾ drain line elbow is designed for use with flexible polytube only. The ¾ drain line elbow can be rotated 180 degrees so the outlet can be orientated to the nearest drain. The same retainer is used for all drain line flow controls for the ¾. Drain line flow controls designed for the ¾ fitting are available for flow rates ranging from 2.6 to 37.9 lpm (0.7 to 10 gpm). An optional 1 straight drain line fitting is available to accommodate drain line flow rates ranging from 34.1 to 94.6 lpm (9 to 25 gpm). This fitting is straight but still connects to the control valve using the same locking clip. The drain line flow control is located between two fitted parts (i.e. the fitting acts as the retainer). The nut is unscrewed to access the drain line flow control.
WS1CI & WS1.25CI Manual Page 11 Water Meter or Meter Plug The water meter is installed on the outlet side of the control valve. The water meter uses a turbine to measure the volume of treated water. The turbine rotates with the flow of water and reports its rate of rotation through Hall effect 5 circuitry to the printed circuit (PC) board. This rotation permits the PC board to record the total volume of treated water and the flow rate. The small centrally located magnet is shielded from water, which substantially reduces iron-fouling problems with the turbine. THIS WATER METER SHOULD NOT BE USED AS THE PRIMARY MONITORING DEVICE FOR CRITICAL HEALTH EFFECT APPLICATIONS. The turbine is accurate to within ± 5% over a wide operating flow rate range (0.95 lpm (0.25 gpm) up to control valve maximums) and has a very low pressure drop. Water used for regeneration is not metered. If the control valve is set to prefill the regenerant, water used between the prefill cycle up to the start of the regeneration cycle is metered. If the control valve is in regeneration mode (e.g. a backwash cycle) and there is a water demand, that water usage is not metered. When facing the front of the control valve, the water meter is positioned on the left-hand side of the control valve. Allow sufficient clearance to clean and repair the water meter without disconnecting the plumbing or disassembling any other parts of the control valve. Control valves can be ordered with a meter plug (i.e. no electronics or turbine) rather than a water meter if desired. Control valves without meters should only be set up for time clock operation (i.e. no water meter, no demand-initiated regeneration). Control valves with water meters provide a wider variety of useful information (see OEM General Instructions for list of information). A unique feature of this control valve is the ability to display actual water usage for the last 63 days. The values are initially stored as ----. This means the value is unknown. As days pass values are stored as 0 for no flow or the actual volume. The counting of the volume starts at the regeneration time. If no regeneration time can be set (i.e. when the valve is set for immediate regeneration) the counting of volume starts at 00:00. Day 1 is yesterday, day 2 the day before yesterday, etc. As new values are added the oldest history disappears. Another unique feature is that the valve automatically calculates a reserve capacity when set up as a softener with Volume Capacity set to AUTO and the Regeneration Time Option set to Normal or Normal + on 0. The actual reserve capacity is compared to the volume capacity remaining immediately prior to the preset regeneration time. A regeneration will occur if the actual reserve capacity is less than the volume capacity remaining. The actual reserve capacity is calculated by using the estimated reserve capacity and adjusting it up or down for actual usage. The estimated reserve capacity for a given day of the week is the maximum value stored for the last three non-trivial water usages (i.e. more than 0.08 M 3 (20 gallons) per day) in seven-day intervals. Mixing Valve The mixing valve is installed on the outlet side of the control valve. The mixing valve is used to blend raw water with treated water. To adjust the blended water, close the mixing valve. Open a water faucet to the desired flow rate. Open the mixing valve until the desired hardness is reached. Close the faucet. Installation Fitting Assemblies The installation fittings are used to connect the optional bypass or the control valve to the plumbing system. These are the installation fitting assemblies available: 1. 1 NPT PVC elbow fitting assembly 2. ¾ & 1 PVC solvent weld elbow fitting assembly 3. 1 straight brass sweat fitting assembly 4. ¾ straight brass sweat fitting assembly 5. 1 plastic male NPT fitting assembly 6. 1¼ plastic male NPT fitting assembly 7. 1 plastic male BSPT fitting assembly 8. 1¼ plastic male BSPT fitting assembly 9. 1¼ & 1½ brass sweat fitting assembly 10. 1¼ & 1½ PVC solvent fitting assembly The installation fitting assemblies are sold in pairs and consist of two fittings, two nuts, two split rings and two o-rings. The installation fitting assemblies and the bypass valve are sold separately from the control valve. Both elbow fittings have a unique drill out feature to allow a ¼ NPT connection to the inlet and/or outlet which can be used for a RO feed, test ports, pressure tap ports, etc. 5 Some semiconductor materials exhibit a phenomenon in the presence of a magnetic field that is adaptable to sensing devices. When a current is passed through one pair of wires attached to a semiconductor, another pair of wires properly attached and oriented with respect to the semiconductor will develop a voltage proportional to the magnetic field present and the current in the other pair of wires. Holding the exciting current constant and moving a permanent magnet near the semiconductor produces a voltage output proportional to the movement of the magnet. Hall effect devices provide a high speed response, excellent temperature stability, and no physical contact.
Page 12 WS1CI & WS1.25CI Manual Bypass Valve The bypass valve is typically used to isolate the control valve from the plumbing system s water pressure in order to perform control valve repairs or maintenance. The WS1 bypass valve is particularly unique in the water treatment industry due to its versatility and state of the art design features. The 1 full flow bypass valve incorporates four positions, including a diagnostic position that allows service personal to work on a pressurized system while still providing untreated bypass water to the facility or residence. Its completely non-metallic, all-plastic design allows for easy access and serviceability without the need for tools. The bypass body and rotors are glass filled Noryl 6 (or equivalent) and the nuts and caps are glass filled polypropylene. All seals are self-lubricating EPDM to help prevent valve seizing after long periods of non-use. Internal o-rings can easily be replaced if service is required. The bypass consists of two interchangeable plug valves that are operated independently by red arrow-shaped handles. The handles identify the flow direction of the water. The plug valves enable the bypass valve to operate in four positions. 1. Normal Operation Position: The inlet and outlet handles point in the direction of flow indicated by the engraved arrows on the control valve. Water flows through the control valve during normal operation and this position also allows the control valve to isolate the media bed during the regeneration cycle. (See Figure 1) 2. Bypass Position: The inlet and outlet handles point to the center of the bypass, the control valve is isolated from the water pressure contained in the plumbing system. Untreated water is supplied to the plumbing system. (See Figure 2) 3. Diagnostic Position: The inlet handle points in the direction of flow and the outlet handle points to the center of bypass valve, system water pressure is allowed to the control valve and the plumbing system while not allowing water to exit from the control valve to the plumbing. (See Figure 3) 4. Shut Off Position: The inlet handle points to the center of the bypass valve and the outlet handle points in the direction of flow, the water is shut off to the plumbing system. If water is available on the outlet side of the softener it is an indication of water bypass around the system (i.e. a plumbing connection somewhere in the building bypasses the system).

Page 14 WS1CI & WS1.25CI Manual OEM General Instructions The control valve offers multiple procedures that allow the valve to be modified to suit the needs of the installation. These procedures are: OEM Cycle Sequence OEM Softener System Setup OEM Filter System Setup Installer Display Settings User Display Settings Diagnostics Valve History Once the OEM Cycle Sequence has been set, the other procedures can be accessed in any order. Details on each of the procedures are provided on the following pages. At the discretion of the manufacturer, the field technician can access all settings. To lock out access to diagnostic and valve history displays and modifications to settings except hardness, day override, time of regeneration and time of day by anyone but the manufacturer, press, NEXT,, and SET CLOCK in sequence after settings are made. To unlock, so other displays can be viewed and changes can be made, press, NEXT,, and SET CLOCK in sequence. When in operation normal user displays such as time of day, volume remaining before regeneration or days remaining before regeneration are shown. When stepping through a procedure, if no buttons are pressed within five minutes, the display returns to a normal user display. Any changes made prior to the five minute time out are incorporated. The one exception is current flow rate display under the diagnostic procedure. The current flow rate display has a 30 minute time out feature. To quickly exit OEM Softener Setup, OEM Filter Setup, Installer Display Settings, Diagnostics or Valve History press SET CLOCK. Any changes made prior to the exit are incorporated. When desired, all information in Diagnostics may be reset to zero when the valve is installed in a new location. To reset to zero, press NEXT and buttons simultaneously to go to the Service/OEM 1 screen, and release. Press and simultaneously to reset diagnostic values to zero. Screen will return to User Display. Sometimes it is desirable to have the valve initiate and complete two regenerations within 24 hours and then return to the preset regeneration procedure. It is possible to do a double regeneration if the control valve is set to NORMAL or NORMAL + on 0 in OEM Softener System Setup or OEM Filter System Setup. To do a double regeneration: 1. Press the REGEN button once. REGEN TODAY will flash on the display. 2. Press and hold the REGEN button for three seconds until the valve regeneration initiates. Once the valve has completed the immediate regeneration, the valve will regenerate one more time at the preset regeneration time.
WS1CI & WS1.25CI Manual Page 15 OEM Cycle Sequence OEM Cycle Sequence instructions allows the OEM to set the order of the cycle. The OEM Softener System Setup or the OEM Filter System Setup allow the OEM to set how long cycles will last. The OEM may choose up to 9 cycles in any order. Cycle Options BACKWASH DN BRINE FILL RINSE UP BRINE (WS1CI ONLY) SOFTENING OR FILTERING END must be used as the last cycle option. The SERVICE cycle should only be used in brine prefill applications. See tables 3 and 4 for examples of typical softener or filter cycle sequences. Prior to selecting dn brine or up brine or not selecting a regenerant cycle direction, verify the correct valve body, main piston, regenerant piston, and stack are being used, and that the injector or injector plug(s) are in the correct locations. See Compliance Table in Service Instructions under Injector Cap, Screen, Injector Plug and Injector section and Figure 6. The up flow cycle may not be used in the WS1.25CI control valve because the V3407 piston is designed for down flow use only. The following is an example of how to set a valve so that when regeneration is initiated BACKWASH occurs first, dn BRINE occurs second, RINSE occurs third, and FILL occurs fourth. END STEP 1CS STEP 2CS Step 1CS Press NEXT and simultaneously for 3 seconds and release. Then press NEXT and simultaneously for 3 seconds and release. If screen in Step 2CS does not appear in 5 seconds the lock on the valve is activated. To unlock press, NEXT,, and SET CLOCK in sequence, then press NEXT and simultaneously for 3 seconds and release. Then press NEXT and simultaneously for 3 seconds and release. Step 2CS Use the or to select 25 for WS1CI or WS1.25CI valve. Press NEXT to go to Step 3CS. Press REGEN to exit OEM Cycle Sequence. STEP 3CS STEP 4CS Step 3CS Selection only matters if a connection is made to the two pin connector labeled DP SWITCH located on the printed circuit board. Following is an explanation of the options: dpon0 - If the dp switch is closed for an accumulative time of 2 minutes a regeneration will occur immediately. dpdel - If the dp switch is closed for an accumulative time of 2 minutes a regeneration will occur at the scheduled regeneration time. HoLd - If the dp switch is closed a regeneration will be prevented from occuring. Press NEXT to go to Step 4CS. Press REGEN to return to previous step. Step 4CS Determine the measurement to calculate volumetric capacity. The choices are: ppm parts per million FH French degrees dh German degrees -na- Using -na- will allow the OEM to directly place the volume of water treated in place of system capacity in the OEM Softener System Setup level. NOTE: If control is going to be used in a filter application any of these settings can be used. Press NEXT to go to Step 5CS. Press REGEN to return to previous step.
